When you do something socially unacceptable because you forget that there are people around. This is anything dumb that you would only do when you're alone, except you do it in public for everyone to point and laugh at you.
Scratching your balls in public is an example of skipping the flump
Person 1: Dude, stop scratching your balls in public
Person 2: Sorry, i just skipped the flump

The act of engaging in wicked, rough anal sex. The word "flump" comes from the sound that the "givers" crotch makes when slapping against the "takers" bum.
I know she's not really into it, so I lubed up good and surprised her with some crazy rumpus flumping!
